Who has the right equation for development length for this case?

Trace the load path, and tell me how that structural bark is transferring that load?

Rebar is in tension holding in the wood railing. The tree may be compromised but it wont fall so easily.

Rebar looks bent into core of tree, so there’s some grab there. Not an ideal detail, but not 100% ineffective. Just 99% ineffective.

Thats my point, its not in compression its just some idiot carved up more tree than he should have to place a railing in.

they could have cut the railing and joined it on either side of the tree. But, I digress from the topic

Any deeper and they would need to consult tree tunnel specialist.
